Bio Butanol Breakthrough

12/11/2009 1:11 PM

Converting co2 & sunlight to a liquid fuel would be a major break through.

Bio butanol is a direct replacement for gasoline

Being able to produce large quanities is the kind of thing the green economy should be about

I have not had a particularly good week, or a particularly good day.

Even this Mac is not doing well.

You may want to look at the BP site.

Seems as if they are in agreement.

Thanks s.udhayamarthandan,

I get various newsletters

Including Chem Info

When I see something new or especially interesting in the energy field I post it.

This is all well and good Garth, but there isn't any mention of the cost per gallon or the BTU content relative to gasoline. If it's not going to be competitive it'll never fly.

No idea about production costs, still in the pre-pilot stage

Draw your own conclusions about the usefulness

Just something interesting to watch for in the future

Re: Bio Butanol Breakthrough

Thank you, garthh for publishing this Science Daily article. For those who do not know, Garthh is producing organic diesel fuel and is a leader in actually producing alternative energy. In other words, he is putting action to work, not just words.

Now, for a suggestion for those of us who would be doing the engineering to design Bio Butanol plants. In the Science Daily article, the UCLA Scientist are suggesting that the plant(s) be built next to fossil fuel burning power plants. This would be an excellent location for sequestering carbon dioxide and since the energy to produce the Bio Butanol is sunlight, this actually make the power plant even greener. However, there is one more excellent location for the Bio Butanol plants and that is the downstream side of Solid Oxide Fuel Cells. The fuel cell exhaust is water and carbon dioxide at approximately 1000ÂșC. The heat in this exhaust is the driving energy for a turbine or sterling engine driven generator which adds 30% to 40% to the efficiency to the SOFC. This exhaust gas is cooled sufficiently at this point for be used to sequester the CO2 in the exhaust to input the Bio Butanol plant.

How can one begin to calculate the efficiency and savings this schema would produce? Regardless of the greenhouse gas controversy, the costs and efficiency of this SOFC plant + Bio Butanol plant, alone would make the development very much worth while.Is it not one of our duties as engineers to work in this direction? Rather than argue whether global warming is real, whether we should drill for more oil, or whether the world is running out of petroleum, why not use our talents to reduce the costs and increase the efficiency of how we produce our fuels that drive industry? Is this not our job in the first place?

So if coal is burnt, the CO2 scrubbed out and the warm CO2 laden water used to produce biobutanol, coal goes from terribly bad for the environment to OK.

Incidentally, left in the ground coal seams tend to pollute the water table, so an environmental case can be made for mining it provided the deleterious effects of it's use can be overcome.

The waste gas stream could also be combined with the (nutrient rich) fly ash to grow algae. This could be used as stock food as well as a source of bio-fuel.

Another possibility for waste from coal fired power is to add limestone to the powdered coal fuel. The resultant fly ash is then a good cement.

Shouldn't we be looking at pollution as wasted opportunity and resources rather as a problem?

Septic, good ideas, why not put them to work? Why not engineer some test models to work out the bugs?

Garthh,

Here is another one for you, this one via NASA's Green Design link:

Let's take this one more step forward, which includes the butanol story but from NASA's greendesignbriefs: http://www.greendesignbriefs.com/gdmbiomass
